After upgrading to 20.0.1, my mouse scrolling speed is slow

I've just updated to 20.0.1 from 19.0.2 and suddenly, the speed of my mouse scrolling has decreased dramatically. When I tried other browsers, it was usual/normal speed but for firefox, it was very slow (i.e around 5+ lines decreased).

I have looked at one of the recent post about this problem (https://support.mozilla.org/en-US/questions/948356?esab=a&s=mouse+wheel+scroll&r=0&as=s) however, even setting mousewheel.enable_pixel_scrolling to "false", it didn't revert back to normal/usual speed.

FYI, this is without smooth scrolling. I don't use this feature due to personal preference.

Help would be appreciate it.

If there is a problem with scrolling on web pages then try to disable smooth scrolling.

Try to disable hardware acceleration in Firefox.

Thank you for the reply.

Like I said, I don't use smooth scrolling at all. It's disabled at all times.

Also, hardware accel is always disabled as well.

I had a similar problem where it seemed like smooth scrolling was always "ON". Whenever I moved my mouse scrollwheel for 1 notch, the page only scrolled for a few pixels. So it looked like smooth scrolling was enabled somewhere even though it was set to "OFF" in Firefox options.

It turned out that it was a Logitech extension that was causing the problem, more precisely Logitech SetPoint software which was smoothing the scrolling and overriding Firefox's settings.

So if you have a Logitech mouse and Logitech SetPoint software installed, go into Firefox menu Tools -> Add-ons, then click on "Extensions" on the left and then find Logitech SetPoint entry and DISABLE it. I did that and scrolling was then back to normal, as configured within Firefox settings.
